A PS Gigabit Ethernet MAC (GEM) implements a 10/100/1000 Mb/s Ethernet
interface (see the figure in PMC MIO[49] and LPD_MIO[12:25]: GEM1 Ethernet), which
connects to TI DP83867IRPAP U198 Ethernet RGMII PHY before being routed to a vertical
dual-stacked RJ45 Ethernet connector J307 (upper receptacle). The RGMII Ethernet PHY is
boot strapped to PHY address (0x01) and Auto
Negotiation is set to Enable.
